book between the walls of the device, thus sub- This invention relatesto improvements in book protectors and has particular reference to aninexpensive, ornamental, transparent, inconspicious protector adapted tobe secured to the book back cover to protect the top, bottom and backthereof from cracking, bending, tearing and premature destruction,ordinarily caused by handling, falls and application of any undue forceor pressure thereto.

I am aware of the fact that certain protectors for books have beenpreviously devised,'but these to my knowledge are of the rigid type,embody heavy bosses or shoulders and are applicable only to heavy books;devices that necessarily areincorporated into the books at the time theyare bound or rebound, protectors that require fastening elements forsecuring the same to the.

book backs, thus marring or defacing the book.

My device on the other hand serves to overcome these disadvantages andinconveniences, and being made of a resilient material embodies thereinmeans for enclosing the material of a stituting a firm and resilientsupport that'will readily withstand and absorb any extraneous pressure,blows and forces. Furthermore, this device not only holds rigid thematerial of the backs of books, thus preventing wrinkling of the same,which is the principal cause of destruction and tearing of book backs,but also presents a firm, resilient surface to the contact of hands orfingers employed in pulling a book from a shelf. Other objects andadvantages will'be apparent during the course of the followingdescription.

In the accompanying drawing forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. 1 is a perspective view of a portionof an open book, showing my.device applied to the book back at the upper end thereof, a section ofthe back being broken away to illustrate the position of the anchor orelongated portion of the device,

Fig. 2 is a side elevation of a portion of a book, showing the device insection and secured to the top and, likewise, illustrating the device inelevation as secured to the bottom of the book, the view beingillustrated on anenlarged scale and is a verticaltransverse section onthe line 22v tion of the book being illustrated ini'dot and dash li I 2.

The protector per se, as'disclosed to'advantage in Fig. 3 is formed froma single blank of celluloicl that is sufiiciently hard and yet resilient5 that will present a sliding surface and effectively save the book backand prevent the same from wrinkling and cracking, etc., as herein beforerecited.

The said protector embodies in its construction, an elongated body 5bent upon itself as at 6 and terminates at its upper end in a lip orextension 7 spaced from the body 5 and lying substantially inparallelism therewith throughout the greater portion of its length. 'Itwill be noted that there is a slight curvature imparted to the body andlip whereby the device more readily conforms to the curvature of thebook back and assures a snug fitof the protector on said book back.

In applying the device to the book 7 the elongated body 5 is firstinserted between the'back of the leaves 8 and inner side 9 of the cover.The lip 7 will then cover the top and a portion of the outer cover ofthe book back. To secure the protector to the book, cement as indicatedby the numeral 10, glue or any other adhesive material, may be employed,although it is obvious that due to the formation of the lip withrelation to the body, any extraneous adhesive medium may be 30 dispensedwith and the device will frictionally engage the book back withoutdanger of accidental displacement.

In Fig. 2 I have illustrated to advantage'the application of the deviceboth to the-top and bottom of the hook, whereby the said parts may bothbe efficiently protected.

While I have specified celluloid as the preferred material,nevertheless-itis obvious th'atmetal having a resilient characteristic,stiffened cloth, stiff cardboard, fibre or similar material maybereadily utilized.

From the foregoingdescriptio-n, considered in connection with theaccompanying drawing, it will be obviousthat I have devised a simple,inexpensive, readily attachable and unique book protector that, due tothe transparent material. employed, will not obscure the material ofthebook back from view, nor detract from its appearance.

It is to be understood that the form' of my, invention herewith shownand described is to be taken as a preferred example of the same and thatvarious changes relative to the material, size, shape and arrangement ofparts maybe resorted to without departing from the spirit of theinvention or the scope of the. subjoined claims.

Having thus described my invention, I claim:-

1. A book back protector formed from a single blank of material adaptedto be secured to the back of a book, said protector embodying in itsconstruction an elongated body member adapted to be inserted between theback of the leaves of the book and the inner side of the back cover, andmeans formed integral with said blank for covering the top and outerportion of the cover and book back. 7

2. A book back protector formed from a single blank of material adaptedto be secured to the back of a book, said protector embodying in itsconstruction an elongated body member adapted to be inserted between theback of the leaves of the book and the inner side of the back cover,means formed integral with said blank for covering the top and outerportion of the cover and book back, said means comprising a lip. formedby bending a portion of the blank upon itself. H

3. A book'back protector formed from a single blank of transparentmaterial adapted to be secured to the back of a book, said protectorconforming to the curvature of the book back and embodying in itsconstruction an elongated body member adapted to be inserted between theback of the leaves of the book and inner side of the book cover, and alip formed by bending a portion of the body upon itself and serving tocover the top and a portion of the outer cover of the book.

4. A book backprotector formed from a single blankof transparentmaterial adapted to be secured to the back of a book, said protectorconforming to the curvature of the book back and embodying in itsconstruction an elongated body member adapted to be inserted between theback of the leaves of the book and inner side of the book cover, and alip formed by bending a portion of the body upon itself and serving tocover the top and a portion of the outer cover of the book,

and means for adhesively securing the protector 20
